Здраствутей, у меня возникла такая вот проблема, когда я задаю вопрос он не состается а выскакивает эта ошибка: "Django: IntegrityError: column user_id is not unique".
# models.py
class Question(models.Model):
title = models.CharField(max_length=120)
content = models.TextField()
pub_date = models.DateTimeField(blank=True, null=False, auto_now_add=True)
views = models.IntegerField(default=0)
slug = models.SlugField(max_length=240, blank=True)
tag = TaggableManager()
user = models.OneToOneField(User, unique=True)
def __unicode__(self):
return self.title
def save(self, **kwargs):
if not self.pk:
self.date_added = date.today()
if self.title and not self.slug:
self.slug = slugify(self.title)
super(Question, self).save(**kwargs)
# views.py
def ask(request):
if request.method == 'POST':
form = AskForm(request.POST)
if form.is_valid():
question = form.save(commit=False)
question.user = request.user
question.save()
form.save_m2m()
return redirect('/question/one_question/' + str(question.id))
return HttpResponseBadRequest()
